24-hour clock
To change top bar clock format from 12- to 24-hour format change
/var/local/system/locale from
LANG=en_US.utf8
LC_ALL=en_US.utf8
to
LANG=en_GB.utf8
LC_ALL=en_GB.utf8
and restart the device.
...
You can achieve the same effect on firmware 5.1 by switching the language from English US to English GB in the settings.
Setting the time zone
By default, the time that the Kindle displays is UTC. If you are in a different timezone:
[root@kindle root]#
mntroot rw
# copy the required files to the Kindle! Most recent Linux distributions contain these files.
[root@kindle root]#
find /usr/share/zoneinfo/
Quote:
/usr/share/zoneinfo/
/usr/share/zoneinfo/zone.tab
/usr/share/zoneinfo/iso3166.tab
/usr/share/zoneinfo/Europe
/usr/share/zoneinfo/Europe/Berlin
|
[root@kindle root]#
ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime
You will first need to copy the respective zone directory/file (shown in bold above) from another Linux system, as /usr/share/zoneinfo/ is initially (almost) empty on the Kindle!
Hope that helps
